I've been a member of Bitcoin Loophole for 9 months now, and have never looked back. The team culture here is friendly and open, with traders from all over the world – it's also one of the biggest! The team approach means that if you have any questions or problems with your trading, someone will be there to help.
I happily recommend Bitcoin Up. I joined a few months ago and have enjoyed it very much. I'm learning a lot and have been trading 2-3 daily. There is a great team and all have become good friends, including the company owner who is pleasant and very helpful when needed.
